Django: 404 page not found

[imhomer]

I met "404" page not found when I try to enter 127.0.0.1:8000/cn/bedroom . It says on the webpage that "C:/Django/final/media/bedroom" does not exist". Why would this happen?

urls.py:

from django.conf.urls.defaults import *
from final import settings
 
from django.contrib import admin
 
admin.autodiscover()
 
urlpatterns = patterns('',
 
    url(r'^admin/', include(admin.site.urls)),
 
    url(r'^cn/', include('final.photo.urls')),
 
    url(r'^cn/(?P<path>.*)$', 'django.views.static.serve',
 
        {'document_root': settings.MEDIA_ROOT}),
 
)

photo/urls.py:

from django.conf.urls.defaults import *
 
from final.photo.views import List, Detail
 
urlpatterns = patterns('',
 
    url(r'^$', List),
    url(r'^/bedroom/', Detail),
 
)
 

photo/views.py:

# Create your views here.
 
from django.template import loader, Context, RequestContext
 
from django.http import HttpResponse
 
from final.photo.models import Image, Audio, Pinyin, SImage
 
from django.shortcuts import render_to_response
 
def List(request):
 
    ShowSImage = SImage.objects.all()
    ShowLink = Image.objects.all()
 
    context = RequestContext(request, {
 
         'ShowSImage': ShowSImage, 'ShowLink': ShowLink
 
    })
 
    return render_to_response('list.html', context)
 
def Detail(request):
    ShowImage = Image.objects.all()
    ShowPinyin = Pinyin.objects.all()
    ShowAudio = Audio.objects.all()
    context = RequestContext(request, {
        'ShowAudio': ShowAudio, 'ShowImage': ShowImage, 'ShowPinyin': ShowPinyin
    })
    return render_to_response('detail.html', context)

detail.html:

{% extends "base.html" %}
 
{% block title %}{{ item.title }}{% endblock %}
 
{% block content %}
 
<h2>{{ item.title }}</h2>
<img src="{{ item.get_image_url }}" />
{% if object.caption %}<p>{{ object.caption }}</p>{% endif %}
 
{% endblock %}

Thanks in advance!
